Troye Sivan's rise to something resembling pop stardom -- to pop-almost-stardom -- has been pretty conventional. Sivan, born in South Africa and raised in Perth, got his start as a 12-year-old on the Australian version of Star Search. From there, he became a child actor. At 13, he played the younger version of Wolverine in the truly garbage superhero movie X-Men Origins: Wolverine. At 15, he began co-starring in a whole trilogy of South African coming-of-age movies called Spud. Sivan was a popular YouTube personality before he signed with a label. His first album had a duet with Alessia Cara. His second album has a duet with Ariana Grande. He's guested on singles from EDM producers Martin Garrix and Zedd. Thus far in 2018, he's performed on Saturday Night Live and as a special surprise guest at a Taylor Swift show. He dates a model. To the extent that there is a book for mainstream pop stardom in 2018, Troye Sivan is going by the book.
